Longitudinal Study to Identify Predictive Factors of Post-thrombotic Pulmonary Hypertension

The current data on the incidence of pulmonary hypertension (PH) are very variable, depending on the different studies designs. There are no data on the prognostic of PH in patients with asymptomatic pulmonary thromboembolisms (PT), neither paucisymptomatic PH, in which without a prospective follow-up would be underdiagnosed. We thought that the prognosis of both clinical forms (PT with or without symptoms) would be similar. The objective of this study is know the real incidence of pulmonary hypertension (PH) post symptomatic and asymptomatic pulmonary thromboembolic (PT).
